10. A lot of Chinese historical literatures chronicle the activities of the Chinese people in the South China Sea. These books include, among others, Yi Wu Zhi (An Account of Strange Things) published in the Eastern Han Dynasty (25-220), Fu Nan Zhuan (An Account of Fu Nan) during the period of the Three Kingdoms (220-280), Meng Liang Lu (Record of a Daydreamer) and Ling Wai Dai Da (Notes for the Land beyond the Passes) in the Song Dynasty (960-1279), Dao Yi Zhi Lüe (A Brief Account of the Islands) in the Yuan Dynasty (1271-1368), Dong Xi Yang Kao (Studies on the Oceans East and West) and Shun Feng Xiang Song (Fair Winds for Escort) in the Ming Dynasty (1368-1644) and Zhi Nan Zheng Fa (Compass Directions) and Hai Guo Wen Jian Lu (Records of Things Seen and Heard about the Coastal Regions) in the Qing Dynasty (1644-1911). These books also record the geographical locations and geomorphologic characteristics of Nanhai Zhudao as well as hydrographical and meteorological conditions of the South China Sea. These books record vividly descriptive names the Chinese people gave to Nanhai Zhudao, such as "Zhanghaiqitou" (twisted atolls on the rising sea), "Shanhuzhou" (coral cays), "Jiuruluozhou" (nine isles of cowry), "Shitang" (rocky reefs), "Qianlishitang" (thousand-li rocky reefs), "Wanlishitang" (ten thousand-li rocky reefs), "Changsha" (long sand cays), "Qianlichangsha" (thousand-li sand cays), and "Wanlichangsha" (ten thousand-li sand cays).
11. The Chinese fishermen have developed a relatively fixed naming system for the various components of Nanhai Zhudao in the long process of exploration and exploitation of the South China Sea. Under this system, islands and shoals have become known as "Zhi"; reefs "Chan", "Xian", or "Sha"; atolls "Kuang", "Quan" or "Tang"; and banks "Shapai". Geng Lu Bu (Manual of Sea Routes), a kind of navigation guidebook for Chinese fishermen's journeys between the coastal regions of China's mainland and Nanhai Zhudao, came into being and circulation in the Ming and Qing Dynasties, and has been handed down in various editions and versions of handwritten copies and is still in use even today. It shows that the Chinese people lived and carried out production activities on, and how they named Nanhai Zhudao. Geng Lu Bu records names for at least 70 islands, reefs, shoals and cays of Nansha Qundao. Some were named after compass directions in Chinese renditions, such as Chouwei (Zhubi Jiao) and Dongtou Yixin (Pengbo Ansha); some were named after local aquatic products in the surrounding waters such as Chigua Xian (Chigua Jiao, "chigua" means "red sea cucumber") and Mogua Xian (Nanping Jiao, "mogua" means "black sea cucumber"); some were named after their shapes, such as Niaochuan (Xian'e Jiao, "niaochuan" means "bird string") and Shuangdan (Xinyi Jiao, "shuangdan" means "shoulder poles"); some were named after physical objects, such as Guogai Zhi (Anbo Shazhou, "guogai" means "pot cover") and Chenggou Zhi (Jinghong Dao, "chenggou" means "steelyard hook"); still some were named after waterways such as Liumen Sha (Liumen Jiao, "liumen" means "six doorways").
12. Some of the names given by the Chinese people to Nanhai Zhudao were adopted by Western navigators and marked in some authoritative navigation guidebooks and charts published in the 19th and 20th centuries. For instance, Namyit (Hongxiu Dao), Sin Cowe (Jinghong Dao) and Subi (Zhubi Jiao) originate from "Nanyi", "Chenggou" and "Chouwei" as pronounced in Hainan dialects.
13. Numerous historical documents and objects prove that the Chinese people have explored and exploited in a sustained way Nanhai Zhudao and relevant waters. Starting from the Ming and Qing Dynasties, Chinese fishermen sailed southward on the northeasterly monsoon to Nansha Qundao and relevant waters for fishery production activities and returned on the southwesterly monsoon to the mainland the following year. Some of them lived on the islands for years, going for fishing, digging wells for fresh water, cultivating land and farming, building huts and temples, and raising livestock. Chinese and foreign historical literature as well as archaeological finds show that there were crops, wells, huts, temples, tombs and tablet inscriptions left by Chinese fishermen on some islands and reefs of Nansha Qundao.
14. Many foreign documents also recorded the fact that during a long period of time only Chinese lived and worked on Nansha Qundao.
15. The China Sea Directory published in 1868 by order of the Lords Commissioners of the Admiralty of the United Kingdom, when referring to Zhenghe Qunjiao of Nansha Qundao, observed that "Hainan fishermen, who subsist by collecting trepang and tortoise-shell, were found upon most of these islands, some of whom remain for years amongst the reefs", and that "[t]he fishermen upon Itu-Aba island [Taiping Dao] were more comfortably established than the others, and the water found in the well on that island was better than elsewhere." The China Sea Directory published in 1906 and The China Sea Pilot in its 1912, 1923 and 1937 editions made in many parts explicit records of the Chinese fishermen living and working on Nansha Qundao.
